Normal vector of plane P  = -2 i + 1 j + 2 k
a) Since the plane Q passes thrpugh (2,0,4) and has normal vector -2 i + 1 j + 2 k 
Thus applying the general plane equation and obtiaining the coeffieicnets, we get: 
nx(x - xA) + ny(y - yB) + nz(z - zC) = 0 
Substitute data and simplify the expression:
